대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2005, Vol.9 No.2 4 95-102 (8 pages)
In the heart, Na-Ca2 exchange (NCX) is the major Ca2 extrusion mechanism. NCX has been considered as a relaxation mechanism, as it reduces global [Ca2]i raised during activation. However, if NCX locates in the close proximity to the ryanodine receptor, then NCX would curtail Ca2 before its diffusion to global Ca2i. This will result in a global [Ca2]i decrease especially during its ascending phase rather than descending phase. Therefore, NCX would... -
